For example, the determination unit 65of the sharing assistant server 11 may be included in either the userterminal 40 or the shared terminal 42.

(Processing/Operation)

Hereinafter, with reference to FIGS. 22 to 29, a description is given ofprocessing/operation of each embodiment.

(Schedule Registration Processing)

Hereinafter, a description is given of a process that the reservationholder A (e.g., name is Taro Riko) registers his/her schedule from theuser terminal 40 to the schedule management server 12. The reservationholder is a reservation person.

FIG. 22 is an example sequence diagram of a process of registering aschedule (schedule registration process). FIG. 23 is an example ofsign-in screen. FIG. 24 is an example of initial screen of the userterminal 40. FIG. 25 is an example of schedule screen. FIG. 26 is anexample of schedule input screen.

At first, when the reservation holder A operates the keyboard 511 of theuser terminal 40, the display control unit 54 of the user terminal 40displays a sign-in screen 530 used for performing the sign-in on thedisplay 506 as illustrated in FIG. 23 (step S11).

The sign-in screen 530 includes, for example, an input field 531, aninput field 532, a sign-in button 538, and a cancel button 539.

The input field 531 is used for inputting a user ID and an organizationID of a user. The input field 532 is used for inputting a password.

The sign-in button 538 is to be pressed in a case of performing thesign-in. The cancel button 539 is to be pressed in a case of cancellingthe sign-in.

In this example case, the user ID and the organization ID configure ane-mail address of the reservation holder A. The user name portion of thee-mail address indicates the user ID, and the domain name portionindicates the organization ID. Further, the input field 531 may be aninput field used for separately inputting the user ID and theorganization ID instead of the e-mail address.

Then, if the reservation holder A inputs his/her user ID andorganization ID in the input field 531, inputs his/her password in theinput field 532, and then presses the sign-in button 538, the receptionunit 52 receives or accepts a sign-in request (step S12).

Then, the transmission/reception unit 51 of the user terminal 40transmits sign-in request information indicating the sign-in request tothe schedule management server 12 (step S13). The sign-in requestinformation includes information received in step S12 such as user ID,organization ID, and password. Then, the transmission/reception unit 81of the schedule management server 12 receives the sign-in requestinformation.

Then, the authentication unit 82 of the schedule management server 12authenticates the reservation holder A using the user ID, organizationID, and password (step S14). Specifically, the storing/readingprocessing unit 89 searches a combination of user ID, organization ID,and password corresponding to a combination of the user ID, organizationID, and password received in step S13, in the user authenticationmanagement DB 8001 (see FIG. 12).

If the corresponding combination exists in the user authenticationmanagement DB 8001, the authentication unit 82 determines that thereservation holder A of request source is an authenticated user.

On the other hand, if the corresponding combination does not exist inthe user authentication management DB 8001, the authentication unit 82determines that the reservation holder A is not an authenticated user(i.e., the reservation holder A is an unauthenticated user). If thereservation holder A is the unauthenticated user, thetransmission/reception unit 81 notifies the user terminal 40 that thereservation holder A is the unauthenticated user. In this example case,the description is given by assuming the reservation holder A is theauthenticated user.

Then, the transmission/reception unit 81 transmits an authenticationresult to the user terminal 40 (step S15). Then, thetransmission/reception unit 51 of the user terminal 40 receives theauthentication result.

Then, in response to receiving the authentication result indicating thatthe authentication result is valid in step S15, the generation unit 56of the user terminal 40 generates an initial screen 540 illustrated inFIG. 24 (step S16).

Then, the display control unit 54 of the user terminal 40 instructs thedisplay 506 to display the initial screen 540 as illustrated in FIG. 24(step S17).

As illustrated in FIG. 24, the initial screen 540 includes, for example,a “register schedule” button 541 to be pressed when a schedule isregistered, and a “view conducted event record” button 543 to be pressedwhen a conducted event record is to be viewed.

If the user presses the “register schedule” button 541, the receptionunit 52 receives the schedule registration request (step S18).

Then, the transmission/reception unit 51 transmits the scheduleregistration request information to the schedule management server 12(step S19). Then, the transmission/reception unit 81 of the schedulemanagement server 12 receives the schedule registration requestinformation.

Then, the storing/reading processing unit 89 of the schedule managementserver 12 searches the event management DB 8005 (see FIG. 16) managed bythe scheduler using the user ID of the reservation holder A received instep S13 as a search key to read out the corresponding scheduleinformation (step S20). Further, the storing/reading processing unit 89of the schedule management server 12 searches the user management DB8002 (see FIG. 13) using the organization ID received in step S13 as asearch key to read out all of corresponding user IDs and all ofcorresponding user names (step S20).

Then, the transmission/reception unit 81 transmits schedule input screeninformation to the user terminal 40 (step S21). Then, thetransmission/reception unit 51 of the user terminal 40 receives theschedule input screen information.

The schedule input screen information includes, for example, scheduleinformation of the reservation holder A, all user IDs, and all usernames read out in step S20. All of user names also include a title(name) of the reservation holder, such as the reservation holder A, whohas input information for the sign-in in step S12.

Then, at the user terminal 40, the generation unit 56 generates aschedule screen 545 (see FIG. 25) and a schedule input screen 550 (seeFIG. 26) using the schedule input screen information received in stepS21 (step S22).

Then, the display control unit 54 of the user terminal 40 instructs thedisplay 506 to display the schedule screen 545 and the schedule inputscreen 550 (step S23).

As illustrated in FIG. 25, the schedule screen 545 includes a scheduleinformation display field 546 used for displaying schedule informationset for the reservation holder A, and a “create meeting” button 547 tobe pressed when creating a meeting schedule. The reservation holder Acan shift from the schedule screen 545 (see FIG. 25) to the scheduleinput screen 550 (see FIG. 26) by pressing the “create meeting” button547 on the schedule screen 545.

As illustrated in FIG. 26, the schedule input screen 550 includes, forexample, an input field 551, an input field 552, an input field 553, aninput field 554, an input field 555, a display area 556, an input field557, an input field 558, a “schedule setting” button 559, and a “close”button 560.

The input field 551 is used for inputting an event name. The input field552 is used for inputting a resource ID or a resource name to be used asa place (e.g., conference room). The input field 553 is used forinputting a scheduled start date/time of execution of event, and ascheduled end date/time of execution of event. The input field 555 isused for inputting a memo such as agenda or the like.

The display area 556 is used for displaying a reservation holder name.

The input field 557 is used for selecting one or more participant namesof participants other than the reservation holder. The input field 558is used for inputting the shared terminal 42 to be used in an event.

The “schedule setting” button 559 is to be pressed in a case ofregistering a reservation. The “close” button 560 is to be pressed in acase of canceling information being input or input information.

Further, the input field 558 used for inputting the shared terminal 42to be used in the event can be configured to present or propose acandidate 561 as illustrated in FIG. 27, for example, by inputting apart of name (user name) of the shared terminal 42. When a user inputsthe information in the input field 558 or selects the shared terminal 42to be used in the event from the candidate 561, the shared terminal 42is set as a device to be used for the event in a device display field562 of the schedule input screen 550 as indicated in FIG. 28.

Further, as to the setting of the device to be used in the event, forexample, as illustrated in the schedule input screen 550 illustrated inFIG. 29, by inputting a place to be used, such as a conference room,into the input field 552, the shared terminal 42 installed in the placeto be used, such as the conference room, may be set as the device to beused in the event.

Then, the reservation holder A inputs necessary information on theschedule input screen 550, and then presses the “schedule setting”button 559.

Then, the reception unit 52 receives an input of the scheduleinformation (step S24).

Then, the transmission/reception unit 51 transmits the scheduleinformation to the schedule management server 12 (step S25).

The schedule information includes, for example, event name, resource ID(or resource name), scheduled start date/time, scheduled end date/time,user ID of each participant, user ID of to-be-used shared terminal 42,and a memo. Although not illustrated in the schedule input screen 550 ofFIG. 25, if a selection of file data of reference material to be used inan event is received from the reservation holder A, the file data isincluded in the schedule information.

Then, the transmission/reception unit 81 of the schedule managementserver 12 receives the schedule information.

Then, if the schedule management server 12 receives the resource ID (orresource name) in step S25, the schedule management server 12 searchesthe resource management DB 8003 (see FIG. 14) using the receivedresource ID as a search key to read out the corresponding resource name(or resource ID) (step S26).

Then, the storing/reading processing unit 89 stores the reservationinformation for the resource name (or resource ID) read out in step S26in the resource reservation management DB 8004 (see FIG. 15) (step S27).The storing/reading processing unit 89 adds one record of thereservation information to the resource reservation management tablestored in the resource reservation management DB 8004 managed by thescheduler registered in advance. The reservation information isconfigured based on the schedule information received in step S25 andthe resource name (or resource ID) read out in step S26.

In an example of the resource reservation management table illustratedin FIG. 15, the item of “user ID of shared terminal” represents theshared terminal 42 set as a device to be used in an event.

Further, the scheduled use start date/time stored in the resourcereservation management DB 8004 corresponds to the scheduled startdate/time included in the schedule information. Further, the scheduleduse end date/time stored in the resource reservation management DB 8004corresponds to the scheduled end date/time included in the scheduleinformation.

Further, the storing/reading processing unit 89 stores the scheduleinformation (event information) in the event management DB 8005 (seeFIG. 16) (step S28). The storing/reading processing unit 89 adds onerecord of the schedule information to the event management table storedin the event management DB 8005 managed by the scheduler registered inadvance.

The schedule information is configured based on the schedule informationreceived in step S25. As to an example of the event management tableillustrated in FIG. 16, the shared terminal 42 having the user ID“u0000” is set as a device to be used in an event.

Further, the scheduled event start date/time in the event management DB8005 corresponds to the scheduled start date/time in the scheduleinformation. Further, the scheduled event end date/time in the eventmanagement DB 8005 corresponds to the scheduled end date/time includedin the schedule information.

With this configuration, the reservation holder A can register aschedule of an event, such as an online meeting, in which the sharedterminal 42 is selected as a device to be used.

(Event Start Processing)

Hereinafter, with reference to FIGS. 30 and 31, a description is givenof a process of holding a meeting with the user terminal 40 of otherparticipant by using the shared terminal 42 in the conference room Xreserved by the reservation holder A (e.g., name is Taro Riko). FIGS. 30and 31 are examples of sequence diagrams indicating a process ofstarting an event.

At first, when the reservation holder A presses a power switch of theshared terminal 42, the reception unit 22 of the shared terminal 42receives a power ON signal from the reservation holder A (step S31).

Then, the display control unit 24 of the shared terminal 42 displays asign-in screen used for performing a sign-in on the display 220 (stepS32).

Then, if the reservation holder A inputs his/her e-mail address andpassword on the sign-in screen, the reception unit 22 receives oraccepts a sign-in request (step S33).

Then, the transmission/reception unit 21 transmits sign-in requestinformation indicating the sign-in request to the sharing assistantserver 11 (step S34). The sign-in request information includes, forexample, the information received in step S33 such as user ID,organization ID, and password. Then, the transmission/reception unit 61of the sharing assistant server 11 receives the sign-in requestinformation.

Then, the authentication unit 62 of the sharing assistant server 11authenticates the reservation holder A using the user ID, organizationID, and password of the reservation holder A received in step S34 (stepS35). Specifically, the storing/reading processing unit 69 uses the userID, organization ID, and password of the reservation holder A receivedin step S34 as search keys to search a combination of user ID,organization ID, and password corresponding to a combination of the userID, organization ID, and password of the reservation holder A receivedin step S34, in the user authentication management DB 6001 (see FIG. 7).

If the corresponding combination exists in the user authenticationmanagement DB 6001, the authentication unit 62 determines that thereservation holder A of request source is an authenticated user.

On the other hand, if the corresponding combination does not exist inthe user authentication management DB 6001, the authentication unit 62determines that the reservation holder A is not an authenticated user(i.e., the reservation holder A is an unauthenticated user). If thereservation holder A is the unauthenticated user, thetransmission/reception unit 61 notifies the shared terminal 42 that thereservation holder A is the unauthenticated user.

In this example case, the description is given by assuming thereservation holder A is the authenticated user.

Then, the storing/reading processing unit 69 of the sharing assistantserver 11 searches the access management DB 6002 (see FIG. 8) using theorganization ID of the reservation holder A received in step S34 as asearch key to read out the corresponding access ID and access password(step S36).

Then, the transmission/reception unit 61 transmits, to the schedulemanagement server 12, reservation request information indicating arequest for reservation information of resource, and schedule requestinformation indicating a request for schedule information of user (stepS37). The reservation request information and the schedule requestinformation include the user ID, organization ID, and password of thereservation holder A received in step S34, and the access ID and accesspassword read out in step S36. Then, the transmission/reception unit 81of the schedule management server 12 receives the reservation requestinformation and the schedule request information.

Then, the authentication unit 82 of the schedule management server 12authenticates the sharing assistant server 11 using the access ID andaccess password (step S38).

Specifically, the storing/reading processing unit 89 searches acombination of access ID and access password corresponding to acombination of the access ID and access password received in step S37,in the server authentication management DB 8006 (see FIG. 17).

If the corresponding combination exists in the server authenticationmanagement DB 8006, the authentication unit 82 determines that thesharing assistant server 11 of request source is an authenticated accessuser.

On the other hand, if the corresponding combination does not exist inthe server authentication management DB 8006, the authentication unit 82determines that the sharing assistant server 11 of request source is notan authenticated access user (i.e., the sharing assistant server 11 isunauthenticated access user). If the sharing assistant server 11 is theunauthenticated access user, the transmission/reception unit 81 notifiesthe sharing assistant server 11 that the sharing assistant server 11 isthe unauthenticated access user.

In this example case, the description is given by assuming the sharingassistant server 11 is the authenticated access user.

Then, the storing/reading processing unit 89 of the schedule managementserver 12 reads out the corresponding reservation information bysearching the resource reservation management DB 8004 (see FIG. 15)managed by the scheduler using the resource ID received in step S37 as asearch key (step S39). In step S39, the storing/reading processing unit89 reads out the reservation information whose scheduled use startdate/time is today.

Further, the storing/reading processing unit 89 searches the eventmanagement DB 8005 (see FIG. 16) managed by the scheduler using the userID of the reservation holder A received in step S37 as a search key toread out the corresponding schedule information (step S40).

In this example case, the storing/reading processing unit 89 reads outthe schedule information whose event start schedule date is today. Ifthe schedule management server 12 is located in a different country orregion from the shared terminal 42, the schedule management server 12adjusts the time zone in accordance with the country or region where theshared terminal 42 is located based on the time zone information.

Then, the storing/reading processing unit 89 searches the project membermanagement DB 8007 (see FIG. 18) using the user ID of the reservationholder A received in step S37 as a search key to read out the project IDand the project name of all of projects including the user ID of thereservation holder A (step S41).

Then, the transmission/reception unit 81 transmits, to the sharingassistant server 11, the reservation information read out in step S39,the schedule information read out in step S40, and all of project IDsand all of project names read out in step S41 (step S42). Then, thetransmission/reception unit 61 of the sharing assistant server 11receives the reservation information, the schedule information, all ofproject IDs, and all of project names.

Then, the creation unit 63 of the sharing assistant server 11 creates areservation list based on the reservation information and the scheduleinformation received in step S42 (step S43).

Then, the transmission/reception unit 61 transmits, to the sharedterminal 42, reservation list information indicating content of thereservation list, and all of project IDs and all of project names (stepS44). Then, the transmission/reception unit 21 of the shared terminal 42receives the reservation list information, and all of project IDs andall of project names.

Then, at the shared terminal 42, the display control unit 24 instructsthe display 220 to display a reservation list screen 230 illustrated inFIG. 32 (step S45).

FIG. 32 is an example of a reservation list screen of the resource. Thereservation list screen 230 includes a display area 231 used fordisplaying a resource name (in this case, place name), and a displayarea 232 used for displaying date of today. Further, the reservationlist screen 230 displays event information 235 to 237 indicating eachevent using a particular resource (e.g., conference room X in thisexample) of the date of today.

The event information is information or data related to theabove-described event. The event information includes, for example,scheduled use start time and end time of resource, event name, and nameof person who has reserved each resource (reservation holder name) foreach event. The event information includes, for example, start buttons235 s to 237 s, or the like, to be pressed if a user designates orspecifies an event to be started, but is not limited to thereto. Theevent information may include participant, actual use start and endtime, communication conditions, calling quality, or the like.

Then, in FIG. 32, if the reservation holder A presses the start button235 s with the pointing device 512, the reception unit 52 receives aselection of an event indicated by the event information 235 (step S51).

Then, the display control unit 24 displays a project list screen 240,illustrated in FIG. 33, on the display 220 based on the project ID andthe project name received in step S44 (step S52).

FIG. 33 is an example of the project list screen 240. The project listscreen 240 includes, for example, project icons 241 to 246 indicatingeach project. The project list screen 240 further includes an “OK”button 248 to be pressed when to confirm a selected project icon, and a“CANCEL” button 249 to be pressed when to cancel a selection of projecticon.

Then, in FIG. 33, if the reservation holder A presses the project icon241 with the electronic pen 2500 or the like, the reception unit 22receives a selection of a project indicated by the project icon 241(step S53).

Then, the transmission/reception unit 21 of the shared terminal 42transmits to the sharing assistant server 11, the scheduled event IDindicating the scheduled event selected in step S51, and the project IDindicating the project selected in step S53 (step S54). The processingof step S54 is a transmission request processing of conducted eventidentification information. Then, the transmission/reception unit 61 ofthe sharing assistant server 11 receives the selected scheduled event IDand the selected project ID.

Then, at the sharing assistant server 11, the generation unit 64generates a unique conducted event ID (step S55).

Then, the storing/reading processing unit 69 stores or manages theconducted event ID generated in step S55, the scheduled event ID, userID and organization ID of reservation holder, and the event informationreceived in step S54 in association with each other (step S56).

The user ID and organization ID of the reservation holder and the eventinformation are IDs and information based on the reservation informationand the schedule information received in step S42. At this stage,information is not yet input in a column of participation or absence ofthe reservation management table (see FIG. 9).

Then, the storing/reading processing unit 69 stores or manages theproject ID received in step S54, and the conducted event ID generated instep S55 in association with each other (step S57).

Then, at the sharing assistant server 11, the transmission/receptionunit 61 transmits, to the schedule management server 12, file datatransmission request information indicating a transmission request offile data registered in the schedule management server 12 (step S58).The file data transmission request information includes the scheduledevent ID received in step S54, the user ID and organization ID of thereservation holder A received in step S34, and the access ID and accesspassword read out in step S36. Then, the transmission/reception unit 81of the schedule management server 12 receives the file data transmissionrequest information.

Then, the storing/reading processing unit 89 of the schedule managementserver 12 searches the event management DB 8005 (see FIG. 16) using thescheduled event ID received in step S58 as a search key to read out filedata associated with the scheduled event ID (step S59).

Then, the transmission/reception unit 81 transmits the file data readout in step S59 to the sharing assistant server 11 (step S60). Then, thetransmission/reception unit 61 of the sharing assistant server 11receives the file data.

Then, the storing/reading processing unit 69 of the sharing assistantserver 11 stores and manages the file data received in step S60 in theschedule management DB 6003 (see FIG. 9) in association with thescheduled event ID received in step S54 and the conducted event IDgenerated in step S55 (step S61).

Then, the transmission/reception unit 61 transmits the conducted eventID generated in step S55 and the file data received in step S60 to theshared terminal 42 to which the reservation holder A has performed thesign-in (step S62). Then, the transmission/reception unit 21 of theshared terminal 42 receives the conducted event ID and the file data.

Further, the transmission/reception unit 21 may transmit an invitationto the event to the user terminal 40 of other participant using aninvitation mail or the like. The attendance request for event includes,for example, various kinds of information for participating (attending)the event started by the reservation holder A.

With this configuration, the other participant can use the participationrequest notice for the particular event to notify his/her participationto the particular event from the user terminal 40 used by the otherparticipant to the sharing assistant server 11 to participate theparticular event, such as the online meeting started by the reservationholder A.

Then, at the shared terminal 42, the storing/reading processing unit 29stores the conducted event ID and the file data in the storage unit 2000(step S63). In step S63, the file data transmitted from the sharingassistant server 11 is stored in a specific storage area of the storageunit 2000. With this configuration, the shared terminal 42 accesses thespecific storage area during the execution of the event, and the displaycontrol unit 24 instructs the display 220 to display the file datastored in the specific storage area.

The specific storage area is a temporary storage destination of dataprovided for each event that is being conducted, and is a storage areaspecified by an arbitrary path (text string) indicating a location inthe storage unit 2000.

Further, the specific storage area is not limited to the configurationprovided inside the shared terminal 42. For example, the specificstorage area may be provided in an external storage device connected tothe shared terminal 42 or in a local server which exists in anon-premise environment and can communicate with the shared terminal 42.

Then, as illustrated in FIG. 34, the display control unit 24 instructsthe display 220 to display a detailed information screen 250 of theselected event (hereinafter, event detailed information screen 250)(step S64).

The event detailed information screen 250 includes, for example, adisplay area 251 used for displaying event name, a display area 252 usedfor displaying scheduled event execution time (scheduled start time andscheduled end time) of event, and a display area 253 used for displayingname of reservation holder.

Further, the event detailed information screen 250 includes a displayarea 256 used for displaying content of memo, a display area 257 usedfor displaying name of scheduled participant, and a display area 258used for displaying identification information (e.g., file name)identifying file data stored in the specific storage area of the storageunit 2000.

The display area 257 displays the name of reservation holder and thename of selected other participant.

Further, the display area 258 displays a file name of file data storedin the specific storage area of the storage unit 2000, that is a filename of file data downloaded from the sharing assistant server 11, andalso displays a file name of file data being downloaded from the sharingassistant server 11.

Further, the event detailed information screen 250 includes a “close”button 259 at the lower right portion of the event detailed informationscreen 250, which is to be pressed when the event detailed informationscreen 250 is closed.

Then, the other participant, who has received the participation requestnotice, sends or transmits a participation notification to the eventfrom the user terminal 40 to the sharing assistant server 11, andparticipates an event such as an online meeting started by thereservation holder A (step S66). Then, the transmission/reception unit61 of the sharing assistant server 11 receives the user ID of the otherparticipant who has participated the event, such as the online meetingstarted by the reservation holder A.

Then, the sharing assistant server 11 inputs a mark of participation orabsence of each participant in the column of participation or absence inthe schedule management DB 6003 (see FIG. 9), that has not been input,and then stores and manages the participation or absence of eachparticipant (step S67).

With this configuration, the reservation holder A and the otherparticipant can start the event (e.g., online meeting) using theresource (e.g., conference room X) and the shared terminal 42. Then, thedisplay control unit 24 instructs the display 220 to display an eventexecution screen.

(Processing during Event)

Hereinafter, a description is given of processing during an onlinemeeting after starting the online meeting, which is an example of event.When an event such as an online meeting has started, the reservationholder A and other participant who are members of a project forcollaboration work can hold the online meeting using a file sharingfunction, a screen sharing function, a voice call function, a video callfunction, a chat function, or the like provided by the collaborationsystem 10.

During the online meeting, the reservation holder A and otherparticipants can use the chat function to transmit a message having amention designating the shared terminal 42, from the user terminal 40 tothe shared terminal 42, with which the function of the shared terminal42 can be controlled from the user terminal 40, to be described later.

FIG. 35 is an example of correlation of message contents of chatfunction with operation contents (functions) of the shared terminal 42,which can be controlled by the message contents. The message contents ofFIG. 35 are contents of messages that are posted using the chatfunction, and may be text or an attached file.

For example, if the message contents of FIG. 35 are set, and a messagecontent is attached with a file of “test.ppt” having a mention, such as“@xx (conference room: electronic whiteboard” (see FIG. 36), asillustrated as a screen image in FIG. 37, the message content indicatesa content of operation displaying the file of “test.ppt” of FIG. 36 onthe shared terminal 42. FIG. 36 is an example of message content postedusing the chat function. FIG. 37 is an example of a display screen ofattached file.

FIG. 40 (40(a), 40(b)) isexamples of a display screen of the shared terminal 42 and a cameraimage.

Further, if the message contents of FIG. 35 are set, and a messagecontent is attached with a mention, such as “@xx conference room:electronic whiteboard” and a text of “view camera image”, the messagecontent indicates a content of operation of sharing a camera image ofthe shared terminal 42 (see screen image of FIG. 40(b)), by the membersparticipating the same online meeting.

Further, the switching between the display image of FIG. 40(a) and thecamera image of FIG. 40(b) can be performed by a button 580 set at thelower left corner of a screen displayed on the shared terminal 42 (seeFIG. 40), in addition to a method using the chat function.

Further, if the message contents of FIG. 35 are set, and a messagecontent includes text indicating an end of meeting, such as “test hasended” as illustrated in FIG. 41, the message content indicates acontent of operation of posting a file of meeting log of “meetinglog.zip”, which is indicated as a message at the lower part in FIG. 41.

The processing for controlling the functions of the shared terminal 42by the participant of the online meeting using the chat function and theconfiguration of FIG. 35 can be implemented by performing a processingprocedure of sequence diagram illustrated in FIGS. 42 and 43.

FIGS. 42 and 43 are sequence diagrams illustrating a process when a userrequests a control of the shared terminal 42 using a chat function.

The sequence diagram of FIG. 42 indicates an example, in which a controlrequest of function of the shared terminal 42 using the chat function isreceived from a user (Mr. A) who participates the same online meeting asthe shared terminal 42. Further, the sequence diagram of FIG. 43indicates an example, in which a control request of function of theshared terminal 42 using the chat function is received from a user (Mr.B) who does not participate the same online meeting as the sharedterminal 42.

As indicated in FIG. 42, if a user (Mr. A) designates the sharedterminal 42 as a mention and transmits a chat message attached with afile to the collaboration system 10 using the user terminal 40, the userterminal 40 posts the chat message (step S100).

Then, the collaboration system 10 transmits the posted message havingthe mention to the shared terminal 42 (step S102). Then, since themention of the received message designates the shared terminal 42, andthe message is attached with the file, the shared terminal 42 determinesthat the shared terminal 42 has received a request of displaying(projecting) the file.

Then, the determination unit 25 of the shared terminal 42 inquires thecollaboration system 10 whether or not the user (Mr. A) who has postedthe message received in step S102 is participating the same onlinemeeting that the shared terminal 42 has participated (step S104). Forexample, the shared terminal 42 transmits identification information ofthe user (Mr. A) who has posted the message to the collaboration system10.

The collaboration system 10 includes, for example, the schedulemanagement table (see FIG. 9) in the storage unit 6000 of the sharingassistant server 11. The schedule management table stores reservationholder name of online meeting, user ID of reservation holder, name ofother participant, and user ID of other participant.

The collaboration system 10 determines whether the receivedidentification information of the user is included in the identificationinformation of the reservation holder and other participant stored inthe schedule management table. If the collaboration system 10 determinesthat the received identification information of the user is included inthe identification information of the reservation holder and otherparticipant stored in the schedule management table, the collaborationsystem 10 determines that the user corresponding to the receivedidentification information is participating the same online meeting.

Since FIG. 42 indicates an example case that the user A has participatedthe same online meeting, the collaboration system 10 returns informationof “Yes” indicating that the user A has participated the same onlinemeeting to the shared terminal 42 (step S106).

Since the user (Mr. A) who has posted the message is participating thesame online meeting of the shared terminal 42, the function control unit31 of the shared terminal 42 performs a control of displaying(projecting) the file attached to the message received in step S102(step S108).

As to the sequence diagram of FIG. 42, the user can operate the sharedterminal 42 from the user terminal 40 by sending or transmitting themessage using the chat function to the shared terminal 42 participatingthe same online meeting.

As indicated in FIG. 43, if a user (Mr. B) designates the sharedterminal 42 as a mention and transmits a chat message attached with afile to the collaboration system 10 using the user terminal 40, the userterminal 40 posts the chat message (step S110).

Then, the collaboration system 10 transmits the posted message havingthe mention to the shared terminal 42 (step S112). Then, since themention of the received message designates the shared terminal 42, andthe message is attached with the file, the shared terminal 42 determinesthat the shared terminal 42 has received a request of displaying(projecting) the file.

Then, the determination unit 25 of the shared terminal 42 inquires thecollaboration system 10 whether or not the user (Mr. B) who has postedthe message received in step S102 is participating the same onlinemeeting that the shared terminal 42 has participated (step S114).

Since FIG. 43 indicates an example case that the user B has notparticipated the same online meeting, the collaboration system 10returns information of “No” indicating that the user B has notparticipated the same online meeting to the shared terminal 42 (stepS116).

Since the user (Mr. B) who has posted the message is not participatingthe same online meeting of the shared terminal 42, the function controlunit 31 of the shared terminal 42 performs a control of not displaying(projecting) the file attached to the message received in step S112.

Then, the determination unit 25 posts, for example, a message contentillustrated in FIG. 44 designating the user (Mr. B) as a mention (stepS118).

FIG. 44 is an example of message content posted using the chat function.In an example of FIG. 44, a message including a mention such as “@Mr. B”and text of “you cannot operate electronic whiteboard in xx conferenceroom because you are not participating the same meeting of theelectronic whiteboard” is set and transmitted.

Then, the collaboration system 10 transmits the posted message havingthe mention to the user terminal 40 operated by the user (Mr. B) (stepS120). Since the user (Mr. B) is not participating the online meetingthat the shared terminal 42 has participated as indicated by the messagecontents of FIG. 44, the user (Mr. B) can confirm that the file attachedto the message posted in step S110 is not displayed (projected) on theshared terminal 42.

As to the sequence diagram of FIG. 43, an operation of the sharedterminal 42 using the chat function from a user who does not participatethe same online meeting can be rejected.

In the sequence diagrams illustrated in FIGS. 42 and 43, the sharedterminal 42 determines that the request is a displaying (projecting) ofthe attached file from the received message content, but is not limitedthereto. For example, the collaboration system 10 can determine that therequest is a displaying (projecting) of the attached file as illustratedin sequence diagrams illustrated in FIGS. 45 and 46.

FIGS. 45 and 46 are sequence diagrams illustrating a process when a userrequests a control of the shared terminal 42 using a chat function.

The sequence diagram of FIG. 45 indicates an example, in which a controlrequest of function of the shared terminal 42 using the chat function isreceived from a user (Mr. A) who participates the same online meeting asthe shared terminal 42. Further, the sequence diagram of FIG. 46indicates an example, in which a control request of function of theshared terminal 42 using the chat function is received from a user (Mr.B) who does not participate the same online meeting as the sharedterminal 42.

As indicated in FIG. 45, if a user (Mr. A) designates the sharedterminal 42 as a mention and transmits a chat message attached with afile to the collaboration system 10 using the user terminal 40, the userterminal 40 posts the chat message (step S140).

Then, since the mention of the received message designates the sharedterminal 42, and the message is attached with the file, thedetermination unit 65 of the collaboration system 10 determines that therequest is a request for displaying (projecting) of the attached file.Further, the determination unit 65 can determine the type of operationrequest using a correlation table (see FIG. 35) that associates themessage contents with the operation contents (functions) of the sharedterminal 42 that can be controlled by the message contents.

Then, the determination unit 65 checks whether the user (Mr. A) who hasposted the message received in step S140 is participating the onlinemeeting that the shared terminal 42 has participated (step S142). SinceFIG. 45 indicates an example that the user (Mr. A) and the sharedterminal 42 have participated the same online meeting, the determinationunit 65 determines that the user (Mr. A) and the shared terminal 42 areparticipating the same online meeting.

Since the user (Mr. A) who has posted the message is participating thesame online meeting of the shared terminal 42, the control request unit67 of the collaboration system 10 requests the shared terminal 42performs a control of displaying (projecting) the file attached to themessage received in step S140 (step S144).

Then, the function control unit 31 of the shared terminal 42 performs acontrol of displaying (projecting) of the file attached to the messagereceived in step S140 in accordance with the control request in stepS144 (step S146).

As to the sequence diagram of FIG. 45, the user can operate the sharedterminal 42 from the user terminal 40 by sending or transmitting themessage using the chat function to the shared terminal 42 participatingthe same online meeting.

As indicated in FIG. 46, if a user (Mr. B) designates the sharedterminal 42 as a mention and transmits a chat message attached with afile to the collaboration system 10 using the user terminal 40, the userterminal 40 posts the chat message (step S160).

Then, since the mention of the received message designates the sharedterminal 42, and the message is attached with the file, thedetermination unit 65 of the collaboration system 10 determines that therequest is a request for displaying (projecting) of the attached file.

Then, the determination unit 65 checks whether the user (Mr. B) who hasposted the message received in step S160 is participating the onlinemeeting that the shared terminal 42 has participated (step S162). SinceFIG. 46 indicates an example case that the user B has not participatedthe same online meeting, the determination unit 65 determines that theuser (user B) is not participating the same online meeting.

Since the user (Mr. B) who has posted the message is not participatingthe online meeting that the shared terminal 42 has participated, thecollaboration system 10 transmits, for example, a message having amention (see FIG. 44) to the user terminal 40 operated by the user (Mr.B) (step S164). Since the user (Mr. B) is not participating the onlinemeeting that the shared terminal 42 has participated as indicated by themessage contents of FIG. 44, the user (Mr. B) can confirm that the fileattached to the message posted in step S160 is not displayed (projected)on the shared terminal 42.

As to the sequence diagram of FIG. 46, an operation of the sharedterminal 42 using the chat function from a user who does not participatethe same online meeting can be rejected.

Modification of System

Although the above described embodiment has described a case where amessage displayed on a chat screen is used, but a message transmittedinternally in the system (not displayed on the chat screen) may be used.Further, the above described embodiment can be also implemented using amessage transmission function different from the chat function.

Although the text chat is described in the above embodiment, the sharedterminal 42 can be operated, for example, using voice. FIG. 47 is anexample sequence diagram illustrating a process when a user requests acontrol of the shared terminal 42 using voice. The sequence diagram ofFIG. 47 indicates an example, in which a control request of function ofthe shared terminal 42 using the chat function is received from a user(Mr. A) who has participated the same online meeting of the sharedterminal 42.

As indicated in FIG. 47, the user (Mr. A) who operates the user terminal40 speaks “capture screen of electronic whiteboard in xx conferenceroom” (step S180).

Then, the user terminal 40 operated by the user (Mr. A) performs voiceanalysis processing on voice data to convert the voice data into textdata (step S182).

Then, the user terminal 40 uses the text data converted from the voicedata by performing the voice analysis processing in step S182 totransmit a chat message designating the shared terminal 42 as a mentionand attached with a file to the collaboration system 10 to post the chatmessage (step S184).

Then, the collaboration system 10 transmits the posted message havingthe mention to the shared terminal 42 (step S186).

Since the processing after step S186 is the same as the processing afterstep S102 in FIG. 42, the description thereof will be omitted. In FIG.47, the user terminal 40 performs the voice analysis processing on thevoice data, but the collaboration system 10 can be configured to performthe voice analysis processing on the voice data.

Further, for example, by using the voice chat function, a voice messagemay be posted, and the voice analysis processing may be performed by thecollaboration system 10 or the shared terminal 42 to determine the typeof operation request from the message content.

Further, for example, after ending the above-described online meeting,as illustrated at the lower part of FIG. 41, the meeting log is postedas a file includes, for example, a screen capture including the contentswritten at the time of ending the online meeting, and audio data/videodata recorded using the microphone 2200 and the camera 2400.

Further, after ending the online meeting, the power supply of the sharedterminal 42 may be turned off, or all the written contents may bedeleted. As described above, no problem occurs as long as the powersupply is turned off or the written content is deleted after ending theonline meeting. However, if the power supply is turned off or thewritten content is deleted during the online meeting, the meeting logcannot be posted correctly.

Therefore, when the shared terminal 42 receives an operation of turningoff the power supply or deleting the written contents (e.g., deletingall information or deleting pages) from a user during the onlinemeeting, the shared terminal 42 may display a user interface (UI)illustrated in FIG. 48 to request the user to confirm whether or not topost the meeting log to the chat. By using the UI illustrated in FIG.48, even if the shared terminal 42 receives the power-off operation orwritten content deletion operation from the user during the onlinemeeting, the shared terminal 42 can post the file of meeting log asillustrated in FIG. 49.
